Handling Fuel
WARNING!
Diesel fuel is flammable and explosive under certain conditions.
• NEVER refuel with the engine running.
• Always refuel outdoors or in a well ventilated area.
• Fill the fuel tank with diesel fuel ONLY. Filling the fuel tank with gasoline may result in a fire and will
damage the engine.
• Remove flammable material containers from the box before filling them with fuel.
• Do not smoke or allow open flames or sparks in or near the area where refueling is performed or
where fuel is stored.
• Wipe up all spills immediately.
• Keep sparks, open flames or any other form of ignition (match, cigarette, static electricity source)
well away when refueling.
• NEVER remove the fuel cap while the engine is running.
• NEVER overfill the fuel tank. Do not fill the tank neck.
• If fuel spills on your skin or clothing, immediately wash it off with soap and water and change
clothing.
